摘要： The purpose of the invention is to provide a former head allowingfor processing long fibres while achieving a carding action and a fibre distribution fulfilling high quality standards, and providing the possibility of adjustments during operation. The former head (2) contains at least one needle roller (6), where a mixture of air and fibres are injected above the horizontal plane in which the centre axis of the needle roller is situated and directly onto the periphery (22) of the needle roller, and which is furthermore arranged with a number of adjustable needle rollers (8,10). With a former head (2) where fibres and air are injected in a controlled and new way, there is achieved possibility of processing longer fibres and maintain a high distribution quality. By using a number of adjustable needle rollers (8,10), there is achieved the advantage that the fibre material go through a carding process during the distribution. This carding process is effected by the action of needles (36) by injection onto the periphery (22) of the stationary needle roller as well as by the subsequent contact with the adjustable needle rollers (8,10).

摘要： The present invention concerns a method for cleaning apparatus part on a binder/glue application apparatus (2) in connection with applying binder/glue (4) on shaped fibre products (6) and an apparatus (2) for application of binder/glue (4) on shaped fibre products (6), where the conveying speed is in the range between 100 m/min and 1000 m/min. By a method/machine according to the invention, selected apparatus parts are applied an aqueous solution of release agent (24) during operation and without reduction in capacity, where the where the release agent (24) solution is applied to the external side (32) of an endless wire, and where behind the application area (22) there is provided a suction slot (34) in which excess release agent solution (24) is collected and conducted further on, preferably to a pipe system (38), a ventilator (36) and a suction box (16). This release agent solution (24) settles on the threads of the wire so that fibres and excess glue do not adhere so well to the wire (12). The collected release agent solution is brought into a pipe system via a ventilator (36) into the suction box system (16) of the spray-wire. Hereby, pipe system (38), ventilator (36) and suction box (16) are internally coated with a release agent film. The atomised and air admixed release agent (52) are thereby acting as a release agent so that dirtying is prevented.
